This mod takes place in a researchs center called "White gate researches center".
This center is similar to black mesa, it is under the ground, and it has security officers etc..
You play as an HECU soldier in this mod and you should search&destroy this center. This center is not filled with zombies or headcrabs or any other things.
The researchers in the white gate researchs center, have found a way to teleport to Xen and they have xaptured some headcrabs. They have managed to take out a virus out of theese creatures and they are planning to make a biological weapon from this virus. But, they are not allowed to work on weapons, because government doesnt want them to do. But, unfortunately, they go on working on this bio-weapon and government learns this, so they ask HECU squad to moake an operation to the base and stop the developement of this bio-weapon.
The commander, finds this mission easy, so he decides to send only one soldier to this center.
And it is YOU! :D
As i said before, you won't shoot any xen creature in this mod except one small part, because this mod takes place before the resonance cascade. You wont shoot any HECU soldiers either. You will shoot scientists and the security officers in that center.
So this mod includes:

Very suprising sequences
A suprise end
A more normal combat(so you shoot people, not mindless zombies)
Some configured weapons
TANK DRIVING!!!
Indoor and outdoor places
Allied soldiers
Hostile barneys and scientists
SUBTITLES (Turkish and english, read the readme file to learn how tho change it)
EXPLODING DOORS WITH C4
and so on...

By the way, i have done this mod ALONE, and it is my first mod, but it is very good for the first time.

ATUHOR'S NOSE:
Uncycylopedia (which is online encyclopidia like wikiped) said I was writing story called Quarter-Life: Halfway to Destruction and dontn't know where come but I decide to write anyway.

CHAPTER ONE: WHAT IT MEANS
Gordon Freechmen was studying in his was studying laboratoried.
Fellow scientist cow-orker Jimm said "Gordon Freemant what are you working on"
"UI have discovered new radoactive isatope but it is so vollatile that it does not have a half-life but quarter-life so we must observe with hasty"
Juts then a headcrab went on Jimms head OH NO WHERE DID HEADCRAB COME FROM! GHordon wents to get his crowbarb ut it was missing so hhad to borrow a claymore sword. He hits teh headcrab and Jimm was okay but his head was cut
"Watch where you swings at me just kidding thanks"
" HAha" They laughed
"Whait oh no where id isotop?"
"UIt is been stoled!"

CHAPTER TWO: THEY REVOCER TEH ISOTROPE BUT THEY DON'T
Gordon and Jimm arrived at teh alien scene where a bad guy from the game said "I have take the isotope and it will cause meltdown!"
"NO, NOT ALL OF DALLAS!" Which swas target of where they were and it was nice place and my friend lives there.
"IF YOU DO NOT AGREE TO MY DEMANS"
"TOO LATE" and the isotope hit quarterlife and teh room was slowly become vaporize
"Ew must escapes out of here fastly" but Jimm was already blowed to smitheroons.

CHAPTER THREE: DESTRUACTION IS IMMINANT
"This is Gordon Freeman how do we contain teh meltdown? I know!"
And he used portals to push henemy headquarters into a portal so Dallas wouldnt melt down and it would only go off harmless in Atlantic ocean.
"Hooray I scucceeded at winning the mission"
"Not so fast, Mr. Gordon"

This is a good mod but I think you should do something about not being able to press movement keys in a tank to avoid crashes.Although it is a good modification.
PS some of you guys are saying the game models should be reskinned.I have an idea but it may not work for some(maybe all)of you.If you have nonsteam half life than change the original models with what you need.It happened to me.
